@Ligt Stimme rfemh tu in time @tetten @nient mit mating mi nf tige snm.

Know all men that I, OTTO EDWARD HENRY STURCKEN, have made a new and useful Improvement in the Constructing and Hanging of WindoW-Sashes, as well as the locking and holding of the saine, of which the following, with accompanying drawings, is a full and clear description. A

The purposes of my invention are to make and hang the sash of windows so that they can be readily removed from the frame for cleaning, and kept securely in any position by a lock or catch. i

Figure 1 represents thc.window, with the sash partly removed, showing the pin A, upon which the beaded side-strip B is hung. the position ofthe lock-catch O shown by the dotted lines. The lower part of thebeaded strip is fastened to the stile, whilst the upper portion swings out to admit theyernoval of the sash, which is grooved upon its edges E E, and worksnpon the side-strips B, dispensing with the parting bead, and securing against the Weather and dust, also preventing the rattling of the sash. Near the top are an eye and hook, D, to which the pulley-cord is attached. The dotted lines show the position of the lock C in the sash, that will firmly hold the sash in any place. There is also a key, vF, to fasten in the swinging bead-strip B. i

Figure 2 shows the adjustable cord-fastening D.

Figure v3 represents thc lock O, and shows its construction. a, spring; b,.lever; c, catch. The construction of the sash` and frame is the same as ordinarily, with the exception of the pin A, beaded side-strip 13,1ock C, hook and eyeI), and grooved sash E, and their arrangements as shown and described.

. Y C'Zaz'ms. 1. I claim a swing sidestrip, B, combined with the adjustable cord-fastening D, and grooved sash E, all constructed and operating as described.

v2. I claim the lock C, in combinationiwith the sash E, strip B, fastening D, as described and for the pur poses set forth. i
